使用Joi，验证布尔值是否为真

Question

Is it possible to validate that a boolean is true using Joi? I've tried using allow , valid and invalid without any luck.

Answer 1

Have you tried something like this:

var schema = Joi.boolean().invalid(false);

Using that schema, the following all populate the error property:

Joi.validate(false, schema);
Joi.validate('false', schema);
Joi.validate('no', schema);
Joi.validate('off', schema);
Joi.validate(0, schema);
